SEWER-TRAP.

SPECIFICATION forming part of Letters Patent No. 395,907, dated January 8, 1889.

Application filed September 10, 1888. Serial No. 285,058. (No model.)

To all whom zit T11/ay concern:

Be it known that I,\VILLIAM KERR, a citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sewer-Traps; and I do hereby declare that the following is a full, clear, and exact description of the invention,wl1ich will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to sewer-traps; and the object ot' the invention is to provide a trap for sinks, bath-tubs, and the like places, where ordinarily the trap is so located as to bc difficult ot approach, and hence difoult to uncouple when cleansing is required. As a rule, these traps, thus located out of convenient reach in dark places, have the further objection ot' being so made that it requires tools and astrong arm,with some mechanical skill, to remove and replace them; and in ease they have been in position for some time, with accumulated rust about the joints, no ordinary tools will su ffice to release them from their seats.v

'l'he purpose of' my invention is to obviate these objections and to lfurnish a trap that can be easily detached and replaced by an unskilled person, and which possesses other vmeritorious and novel features and advantages, all as shown. and described, and particularly pointed out in the claims.

In the accompanying' drawings, forming part of this specification, Figure l is a side elevation of my improved trap. Fig. 2 is a vertical section ot' the same on line .ir er, Fig. l. Fig. 3 is a vertical section of the trap at right angles to the section shown in Fig. 2. Fig. 4 is a perspective view ot' the top of the trap; Fig. 5, a perspective view ot the yoke which supports the cup of' the trap, and Fig. 6 is a view of the connecting-bolt.

It will be noticed that the trap proper consists of two parts or sections, 2 rlhe inletpipe l and discharge-pipe 5 are shown as connected with the top section, and may stand in the position to said section, as shown, or in any other convenient position, according to the connections to be made.

Section il, consisting of what is termed the Lcup ot the trap, has a central diaphragm, 6, extending from its top edge down, say, about three-fourths the depth of the cup, thus leaving ample passage for the water beneath the diaphragm vfrom the inlet to the outlet side of the trap. The top of the diapl1ragm,which is even with the edge of the cup, is preferablyY widened so as to be more easily packed, to prevent escape of fluid or gas from one chamber to the other on the respective sides of' the trap.

i The form of trap shown here is supposed to be madeof lead. It' of lead or the like sof't metal, I solder a brass band, 7, about the top of the cup, which band extends above the edge of the cup and outside and closely around the downwardly-projecting edge of the upper section and practically to a level with the level of the outflow, so that thereby when the cup is removed to be cleansed the waternormally standin therein will not overflow, but may be carried bodily away an d emptied. Ordinarily in disengaging cups from traps the act is unavoidably attended by the spilling or runnin out of' a considerable quantity of' water, which for many reasons it is desirable to avoid. This l do practically avoid by forming my cup with a band, as shown. In case a brass trap were used the band might be cast therewith as a projecting flange or outer edge ot the cup. A packing, 8, o'f leather or other suitable material, is interposed between the upper and lower sections, 2 3, round theircdgc as well as across the center.

To complete the separation of the trap into inlet and outlet chambers having communication only through the bottom of the cup, itl

is necessary also to have a diaphragm in the upper section matching with the diaphragm in the lower section. In this case, to subserve a still further purpose, this diaphragm 9 is double, and extends transversely of the top section from side to side, with an open space or slot, l0, between the walls thereof'. Along their lower edge the walls are united, thus forming a wide bearing-surface to match the top of the lower diaphragm.

Now recurring to the objection to traps that are diiiicult to release and replace without special tools and the awkwardness of approach in dark and obscure places, Ihave conceived the idea of remedying this objection by supplying connecting mechanism, which answers every purpose of closing to form a IOO seal against water and sewer-gas, and yet ma .v 'he quickly and easilyv released or refasliened hy a woman or even a ehild ot' years and iutelligenee. 'lo lihis end the eonstruetion eonsists in a yoke, ll, formed ol' two parts eonneeted h v a wire, l2, or the like, so that 1lw are pivotally and loosel' \Y united and held, as seen in Fig. 2, hetween nuts lil on 1humh-, This yoke oeeupies the slot lll,

serew ll. which is (allai-ged immediatelyl at ils top'eenter, Forming an angular rei-ess, in whieh the nuts lil are seated and lwld from turning, hut are free 1o rise and l'all on the serew llA when said serew is turned lo loosen or l'asten the enp Il.

lt will he seen 1ha1 eaeh arm ol" the yoke has a eateh, whieh engages a pro'ieelion, lo, on the hrass follar or hand on the eup, so that when the lhumh-serew is turned lo raise the inner arms of the yolcelhese ealehes will engage the lugs ll' and l'asl'en the eup, and wlwn turned the opposite wa'v will release said arms and allow 1he eup to he 1urned sligldly in a` horizontal direet ion to he disengaged and renfloved.

It will also he seen that the lhumh-.serew has a hearing, i7, whieh ^x1e1nls aeross the slot lll a1 1he hotlom ol` tlw reeess, and ex- 1 tending up l'rom this hearing on either side thereol-say ahout: one-third tlw depth ol` the reeess-are shouhlers le. (Seen elearl)V in Fig. 2.) (ln the top ot the tra-p the thumhsel-ew passes through. a (follar or washer, lll, which is soldered to its position. Then when the thumh-serew is turned it simply turns in its hearings and the nuls earryv the inner ends olf the 'volte-arms up or down. served that wlwn 1he nuls are earried helow a eertain position, as in releasing theeup, the

rohe-arms will hear against the shoulders 12s. and thus he loreed oi'llward atltheir oulerextremities; or a person ean hiv raising and p lo\\'tf\ring the thumh-nul iu its hearings h v l immediateljr heueath the diaphragm in the one hand throw said arms outward or inward at 1lwir outer extremities lo engage or l t l dxsengage the lugs on the eup, as when 1t 1s t desired lo attaeh or detaeh said cup. ln this wayv a person is enahled lo handle the eup with one hand and the seeuring meehanism h v the other, and this is a matter ot` great eonven ienee.

The diaphragm need not he plaeed direel ly v l1 will he oh- 2 and a loek in the transverse slol lo hold the llavinthus described my invention, what l l claim as new, and desire to seeure hy Letters atent, is

1l. A sew fwtrap eonsist ing ol' a fixed upper seelion having the inlet and the outlet, pipes whollv eonneetetl therewith, a detaehahle lower set-tion, and a diaphragm extending down through the eenler ol the trap near 11o the hotloin o1' the lower seelion, suhstantially as set l'orl'h.

L. A sewer-lrap eonsisting ol' two sections, eaeh seetion hi'tvng part ol' a eenlral vertical t'liaphragm lformed integral therewith and meeting suhslanl iall v on the lino ol' the joint hetween the seetions, \\'hereh.\fv the water en tering upon one side ol' lhe trap is foret-d henealh the diaphragm 1o eross 1o 1he other side, sullstantially as set l'orlh.

il, ln a sewer-trap, a slalionarv upper seetion having the inlet and outlet pipes ot' the trap, a detaehahle lower section, a eentral diaphragm, a part olf whieh is l'ormed in each seetion, and arms sl'lmiortedon the upper seetion and engaging the lower seet'ion, wherelw said sections are held together, sul)sl'autially as set forth.

-.l. A sewt-fr-trap etmsistiug oll two seetions with a (liaphragm, a part oli" which is formed in eau-h seetion, a projet-ting rim on the lower seetion, and paeking around said rim and hetween the parts ot' the diaphragm, substan- 1'iall v as set l'orth.

5. lIn a sewer-trap lornwd in two seetions, an upper seetion having a transverse slot., the
